My avatar is kind of my ideal of beauty. I suppose she could be made even prettier, like with more of a Lolita look, with ribbons and bows and ruffles and pastels (but not a longer skirt). Her hair could be improved a little by being longer and with big Lolita curls.
I remember seeing a woman briefly on tv maybe 20 years ago who looked so beautiful to me that I could hardly stand it. It felt so uplifting and heavenly (and I felt a little embarrassed for her, surrounded by mere mortals). I suppose actual angels look that good.
It's not my goal to look perfect though. I just like to appreciate beauty. But personality seems to be the most important part of beauty. A loving personality. Attaining such a personality is a more worthy goal, I suspect. I like to appreciate beautiful personalities. I love to cry tears of joy over such beauty.
